Abstract
Description
- Rail cars, and particularly bi-level rail cars, are equipped with mesh wire grates to which vehicles such as automobiles and trucks are secured during transport on the rail cars. The preferred method of securing the vehicles on such rail cars has been with chocks such as shown in U.S. Pat. Nos. 5,302,063 and 5,312,213 commonly referred to as “Holden Chocks”.
- The introduction of short wheel-base high center of gravity “cross-over” vehicles has resulted in a great number of instances of vehicles jumping the chocks. In recent years, there has been an effort by the railroads, auto manufacturers, and suppliers to develop tie down systems to halt the increased incidences of jumped chocks.
- Recently, other systems with chocks have been developed such as shown in U.S. Pat. No. 6,851,523 and U.S. Published Application 2008/0232919. Also, a product manufactured by the Holland Company is known comprised of a chock with a self-retracting strap and hook.
- All the known systems currently in use combine plastic and steel parts, and are large and weigh as much as 12 pounds. Only the Holland Company device incorporates a strap over the tire to restrain vertical movement of the tires associated with the vehicles.
- A winch for tightening a strap is illustrated, for example, in design U.S. Pat. No. 346,258.
- Previous chock designs have not taken into consideration the industry's field consumption requirements wherein underbody and wheel rail clearance have been reduced making it difficult to install the large wheel chocks. Ideally, a tie down should work in an area defined by a vertical tangent to the tire. But again, the device should have as low a profile as possible.
- It is an object to provide a tie down system for securing vehicles to wire grates for transport with a system which will prevent jumped chocks, is convenient to use, is relatively inexpensive, and is reliable, but which is compatible with the use of existing wire grates.
- In a vehicle tie down system and method for securing a vehicle to a wire grate, a strap is positioned over and around a portion of the vehicle tire. A connection assembly connects to a first end of the strap. A winch assembly connects to an opposite second end of the strap. Both the connection assembly and the winch assembly have a frame, a hook member, a grate lock member, and a gravity lock member. The winch assembly also has a mandrel and a mandrel locking unit.

Thefront hook member 25 and thegrate lock member 26 engagerespective grate wires 15 as explained further hereafter. Thegravity lock member 28 prevents movement of thegrate lock member 26 when engaged againstmember 26. - Further details of the
winch assembly 19 will now be explained with reference toFIGS. 3 , 4 and 5. - The
winch assembly 19 has themandrel assembly 22 formed of themandrel 30 with theslot 31. A gear 29 withgear serrations 29A is connected at each opposite side of the mandrel. Outer ends of the mandrel havehexagonal members mandrel assembly 19 is retained in respective apertures in side walls of awinch frame 36. - The
pawl unit 23 has twopawl arms 33A, B and therespective pawl tooth 34A, B, and rotates about abolt 35.Pawl unit 23 is spring biased by aspring member 37 having oneend 37A biased against apush surface 6 onpawl arm 33. The spring is wound as shown by winding 37B around thesame bolt 35 which retains thepawl unit 23. Theopposite end 37C of thespring member 37 engages in aretention slot 38A or 38B inrespective sidewalls push surface 6 hits side portions offrame 36. - Grate lock member 21 (also shown in separate detail in
FIGS. 9A and 9B ) is attached by abolt 40 having asecurement locknut 5 throughsidewalls frame 36 for pivoting operation. Thegrate lock member 21 attaches to thebolt 40 at anaperture 39. Thegrate lock member 21 has three gratewire engagement notches 42A, B, C onrespective protrusion portions 21A, B, C. - The
front lock member 21 has threehook portions base member 46 which is a separate piece attached to theframe 36, such as by welding. - The
gravity lock member 9 is shaped like the letter “D” with twoears 9A, B for mounting, and as shown most clearly inFIGS. 10A and 10B has ahandle portion 13 at one end,side portions bridge portion 9E and anabutment surface 47 for engaging against aback surface 8 of thegrate lock member 21, and pivots atapertures 45A, B about abolt 44 secured with alocknut 44A. - Details of the
clevis assembly 24 are illustrated inFIGS. 6 , 7, and 8. Theclevis assembly 24 has aframe 48 havingapertures 70A, B for receiving theclevis pin 27 comprising a bolt passing throughapertures 70A, B in theframe 48 and secured by alocknut 49. The grate lock member 26 (which has the same construction asgrate lock member 21 of the winch assembly) has gratewire engagement notches 50A, B, C and is secured at anaperture 51 for free rotation about abolt 52 secured bylock nut 63. The gravity lock member 28 (which has the same construction asgravity lock member 9 of the winch assembly) has ahandle portion 56 at one end and which rotates about abolt 58 received through respective apertures inframe 48. Thegravity lock member 28 has anabutment surface 59 for abutting against aback surface 7 oflock member 26 when in the locking position. Afront hook member 25 hashook portions base member portion 54 which is integral withframe 48 and a wiregrate engagement surface 55 ofbase member 54. - A mounting engagement of the
winch assembly 19 at any desired position on thewire grate 13 resting onsupport surface 12 will now be described with respect toFIGS. 11A , 11B, and 11C. InFIG. 11A , thegravity lock member 9 is raised by itshandle portion 13, thus allowing rearward pivoting of thefront hook member 20. By tilting thewinch assembly 19, thehook portions wire 15A of thewire grate 13. - As shown in
FIG. 11B , thewinch assembly 19 is now tilted down until it rests on thewires 15 of thegrate 13. Then, as shown inFIG. 11C , thegravity lock member 9 is released which then pushes thegrate lock member 21 such that theengagement notches 42A, B, C engage with agrate wire 15B. In this position,abutment surface 47 of thegravity lock member 9 abuts against theback surface 8 of thegrate hook member 21 and thus locks it in place. - The
clevis assembly 24 engages with thegrate 13 in similar fashion as illustrated inFIGS. 12A , 12B, and 12C. - As shown in
FIG. 12A , theclevis assembly 24 is tilted back towards the vehicle tire so that thehook member 25 engages thetransverse grate wire 15C. While this is occurring the operator pulls thegravity lock member 28 upwardly by use ofhandle portion 56, thus allowinggrate lock member 26 to be rotated back away from the tire. As shown inFIG. 12B , theclevis assembly 28 is then rotated down into a horizontal position. Thereafter inFIG. 12C , handleportion 56 of thegravity lock member 28 is pushed downwardly or falls by gravity which causes the contact of theabutment surface 59 of thegravity lock member 28 to contact theback surface 7 of thegrate lock member 26 forcing the bottom end where thegrate notches 50A, B, C are located to move forwardly away from the tire to engagetransverse grate wire 15D in a locked position. - After the clevis assembly and winch assembly have been locked in position,
strap assembly 16 is threaded over thetire 11 and theend 16A ofstrap 6 is threaded into themandrel slot 31. The mandrel is then turned on the winch assembly in a counterclockwise direction for the arrangement ofFIG. 1 to tighten the end of theweb 16A against itself as it winds on the mandrel. Thepawl tooth gear mandrel 30 to hold it in a position to maintain tension on thestrap assembly 16. - As may be appreciated, the tie down system is adaptable for different sized tires since the winch assembly and clevis assembly may be located and engaged at appropriate locations depending on the size of the tire. Thus, the vehicle may be secured to the grate at various locations in view of the flexibility connection of placement and engagement of the winch assembly and clevis assembly on the grate.
- The tie down system also prevents chock jump by the tire by use of the strap assembly.
- The tie down system is easy to operate in view of its simplicity. Also, reliability is improved in view of the relatively small number of moving parts involved in the system.
- The design of the clevis assembly and winch assembly is simplified allowing reduced manufacturing and material costs.
- Alternative designs may be employed for securing the mandrel rotation and for releasing the mandrel.
- Preferably, the winch assembly overlies approximately four of the transverse grate wires when locking to the first and fourth grate wires while resting on the second and third transverse grate wires. However, the longitudinal dimensions of the winch assembly may vary to encompass a different number of the grate wires.
- Preferably, the clevis assembly utilizes two adjacent transverse grate wires. However, longitudinal dimensions of the clevis assembly could vary to overlie more than two grate wires.
- Further changes may be made to the strap assembly, winch assembly, and clevis assembly such as in the shape of the gravity lock member, grate lock member, and hook member of the winch assembly or clevis assembly.
- The clevis assembly, grate, and winch assembly may be constructed primarily of steel parts, although in some applications, some or more of the parts may comprise harden plastics or other materials.
- The
strap assembly 16 preferably employs a polyester webbing orstrap 6 although potentially other materials may be employed. A width of the webbing is approximately 2 inches. This may vary in a range from 1 inch to 4 inches. - Although a preferred exemplary embodiment is shown and described in detail in the drawings and in the preceding specification, it should be viewed as purely exemplary and not as limiting the invention. It is noted that only a preferred exemplary embodiment is shown and described, and all variations and modifications that presently or in the future lie within the protective scope of the invention should be protected.
